What's your idea on monetizing these websites?
Unless you can convince people to pay for your service, you can either openly use them as advertising platforms or you can be sneaky and sell your data to advertisers behind the scenes.
Doing this is way too risky. It puts your company at risk to secretly sell this data. Imagine if word slipped about this. It could easily landslide into losing half your user-base and eventually the rest of them.
